Application October 28, 1954, Serial No. 465,282

4 Claims. (Cl. 15-261) The present invention relates to janitorial implements and more particularly to a device for pressing water out of a mop.

Heretofore various expedients have been used for wringing water or other liquid from a mop but the prior art structures have not been entirely satisfactory because of the expense of manufacture, the excessive frictional forces to be overcome, and the excessive weight resulting in undue tiring of the workman.

An object of the present invention is to provide a mop wringer which will avoid the deficiency of the prior art and result in more effective removal of water.

A further object is to provide a mop wringer device in which the movable members are moved by a pulling action rather than by a pushing action.

A further object of the invention is to reduce the number of partsrequired in the manufacture of an efiicient mop wringer.

Other and further objects will be apparent upon reference to the accompanying drawings wherein:

Fig. 3, a section taken .on line 3-3 of Fig. 1 corresponding to the showing in Fig. 2;

Fig. 4, a section taken on line 4-4 of the mop wringer in mop receiving position;

Fig. 5, a sectional detail taken approximately on line 5-5 of Fig. 1; and

Fig. 6, a section taken on line 6-6 of Fig. 5.

Briefly, the present invention includes an upstanding frame having slotted ends and a perforated front and back with a bottom movably mounted therein and a pair of movable pressing members mounted in the slots of the end members so that the pressing members may move to positions above the front and rear walls and downwardly to a mop wringing position. Means are provided for simultaneously moving the bottom upwardly and the pressing members downwardly for wringing a mop positioned within the frame. Means are also provided for supporting the mop wringer on a chair.

Referring more particularly to the drawings, a pair of end plates 10-10 are arranged in spaced substantially parallel relation and are connected together by means of a front plate 11 and a rear plate 12 which are retained in place by bolts 13-13 extending through rolled over top and bottom portions of the front and rear plates thereby providing a rigid mop receiving frame. An arcuate shaped bottom 14 is positioned within the frame and is supported on rods 15-15 which extend through inverted J-shaped slots 16-16 formed in the end plates 10 by bending a portion of the plates into outwardly extending webs defining the edges of the slots. Collars 17 provided with inwardly extending projections 18 are tates Patent mounted on the rods outwardly of the end members thereby causing the arcuate shaped plate 14 to move with the rods 15.

Also mounted in the slots 16 are front and rear pressing members 19-19 of generally U-shape with flattened bight portions reinforced by a skeleton Web 20 and having outwardly extending guiding webs 21 slideably received in the slots 16 and an outwardly extending lug 22 -projects beyond the guiding web 21 and outwardly beyond the ribs forming the slot 16.

The end plates 10 are provided with centrally located slots 23 and 24 and the end plates are also provided with guide channels 25-25 and a top web 26-26 reinforcing the channel. An inverted T-shaped member 27 is provided with a slot 28 through its stem and laterally extending downwardly diverging slots 29 formed on the horizontal portion thereof of which slots 29 receive lugs 22 for causing movement of the pressing members 19. A rearwardly extending portion 30 of the T-shaped member is provided with a slot 31 for engagement with a crank pin. Each T-shaped member 27 is secured to its end plate for sliding motion by means of a lug 32 fixed to the corresponding end member by means of a bolt 33 or the like thereby providing for vertically guided movement of each T-shaped member 27.

A rock shaft 34 is pivotally mounted in the end members by means of bearing rings 35 and upon each end of the rock shaft 34 a crank disk 36 is fixedly attached carrying a crank pin 37 for engagement into the slot 31 of the T-shaped member and carrying a second crank pin 38 for co-operation with a slot 39 formed in an inverted Y-shaped plate 40 which is also provided with another slot 41 in the stern portion thereof which receives the guiding lug 32, the Y-shaped plate 40 being retained by means of a washer 42 held in place by the screw 33. The arms of the Y-shaped plate are provided with'apertures which receive the outer ends of rods 15, the rods being secured to the plate 40 by means of screws 43. The rock shaft 34 is operated by means of a handle 44 having a hand grip thereon and fixedly secured to the rock shaft 34 by any suitable means such asa taper pin, bolt or the like.

The end plates 10 are provided with rearwardly and downwardly extending projections 45 forming hooks for engagement with the top edge of a pail and the plates 10 include downwardly projecting extensions which are connected by means of a curved band 46 for engagement with the inner periphery of a pail or bucket whereby the mop wringer is retained in position on a pail for use.

From the above the operation of the present invention is believed to be obvious, and it will be apparent that in use, the wringer is arranged as shown in full line in the drawings and a wet mop inserted in the frame with the mop handle projecting upwardly therefrom the wringer handle 44 is rotated to the dotted line position thereby moving the inverted T-shaped members 27 downwardly and carrying the U-shaped pressing members 19-19 to the dotted line position, the pressing members being pulled by the action on the lugs 22 co-operating with the slots 29 thereby reducing the side thrust on the edges of slots 16. The bottom 14 is simultaneously raised by means of the inverted Y-shaped plate 40, the crank disk 36 causing the respective motions of the T- shaped member and the Y-shaped plate by the reaction of crank pins 37 and 38 with the slots 31 and 29 respectively. When the wringing operation has been completed, the handle 44 is moved to the full line position and the dry mop removed for use.

It will be obvious to those skilled in the art that various changes may be made in the invention without departing from the spirit and scope thereof, and therefore, the invention is not limited by that which is shown in the drawings and described in the specification, but only as indicated in the appended claims.
